DESCRIPTIONS OF CERTAIN CHALCIDOID PARASITES. 23 



PLEUROTROPIS ORIENTALIS, new species. 



Female.— Length, about 1.5""°. Bronzy black, with green or 

 purple reflections, the vertex and base of abdomen more greenish, 

 the metathorax distinctly green; vertex with coarse thimblelike 

 punctures, the frontal declivity above transverse groove smooth, 

 below furrow with finer punctures, those below the insertion of the 

 antennae still finer; antennae brown; mesonotum reticulate, parap- 

 sidal furrows not very apparent; scutellum reticulate all over, 

 basally the lines more regular and longitudinal; metathorax smooth, 

 median and lateral carinae distinct; femora green, tibiae testaceous, 

 tarsi more whitish; first segment of abdomen medially at apex and 

 following segments finely punctured. 



Male. — Unknown. 



Habitat. — Japan. 



Described from 5 specimens reared from Glyptaimnteles japonicus 

 at the Gipsy Moth Parasite Laboratory, from material received 

 from Prof. Trevor Kincaid and Prof. S. I. Kuwana. 



Type.— C&t. No. 12975, U. S. National Museum. 



PLEUROTROPIS HOWARDI, new species. 



Female. — Length, about 2™"*. Green, with bluish reflections, the 

 sides of the scutellum, the apical part of the parapsidal areas, and 

 the pleurae purplish-black; face below the transverse furrow bluish, 

 with fine thimblelike punctures down to the insertion of antennae, 

 below this still more finely and weakly punctured ; above the furrow 

 ^\dth coarse thimblelike punctures; antennae green; pubescence of 

 eyes distinct; mesothorax coarsely reticulate, the parapsidal fur- 

 rows not very distinct anteriorly, posteriorly formed by triangular 

 depressed areas which resemble scars, each with a»single setigerous 

 puncture; median lobe of mesonotum strongly emarginate at apex;

 late, leaving the median basal area smooth; metathorax smooth,

 first segment of abdomen basally smooth, green, beyond this the 

 abdomen purplish-black and finely punctured; legs green, the tarsi 

 white, apically brown. 



Male. — LTnkno wn . 



Habitat. — Japan. 



Described from 8 specimens reared from cocoons of Glyptapanteles 

 japonicus at the Gipsy Moth Parasite Laboratory, from material 

 received from Prof. Trevor Kincaid and Prof. S. I. Kuwana. 



Type.— Cat. No. 12976, U. S. National Museum. 



Named in honor of Dr. L. O. Howard, under whose direction the
